Research on Swimming Stance Classification and Drowning Early Warning Technology Based on Acceleration Analysis

In this paper, we propose and validate a wearable device-based pool drowning early warning technology: a waterproof wristband based on Arduino intelligent development board is produced, and acceleration sensors and a wireless communication system are deployed on the wristband; the wristband sends the sensor data to the swimming pool early warning processing terminal; the terminal analyzes the acceleration data to complete the identification of the swimming posture, and makes an early warning of abnormal swimming posture and potential drowning behaviour, reminding the pool safety personnel to intervene. The above study shows that the drowning early warning program based on the waterproof bracelet and pool management terminal provides safety for swimmers and saves pool management costs, which has strong feasibility and great application potential.
